I don’t trust anyone since the last girl lied and deceived me?

We weren’t dating and I wouldn’t call her and I friends. She just lied about a lot of things and played mind games with me. I caught onto her lies a few weeks. I eventually got tired of her toxic behavior and now I don’t trust anyone anymore when it comes to friendship and dating. I’m not interested in dating anymore not based on this , but based on how dating is. I have become guarded and cautious of who I talk too and allow around me because of this if anything.

I haven’t dated in over 5 years because off how selfish dating has become. I’m still hurting about the fact she lied and played mind games when I wasn’t expecting anything from her , but friendship. Honestly what I thought we were building , but I think she wanted friends with benefits and luckily we never had sex or met for that. I wouldn’t have sex with anyone I’m not dating and committed too.

This wasn’t anyone I dated less more met. I normally meet people online for friendship or networking, but due to this situation I don’t care too meet anyone else online for friendships because I don’t date anymore because how dating is. If someone miraculously met me for a relationship it’ll be the only way and it would have to be face to face. This person hurt me very badly to the point she was deceptive, manipulative, and a liar who preyed on me. I don’t trust anyone and have become guarded
